Backitude

Backitude is a light-weight and efficient Android 2.2+ application used to determine the position of your device and send the location to Google for use in the Google Latitude and Google Location History systems. Backitude can be used in conjunction with the built-in Google Maps location detection service or completely replace it. (recommended for better battery life).

Detect locations using GPS, Wi-Fi network locations, and/or cell tower triangulation locations. Send values to your Google account seamlessly in the background. The application allows the user to control your updating and accuracy options, and allows you and your friends to force updates on each other when an up-to-date current location is really needed.

Offline Storage is available to store location values and upload in bulk at a future time, when Wi-Fi is available if desired.

Widget launches Google Latitude friends list to replace Google Latitude shortcut.

Minimum accuracy config provides a min requirement in location accuracy for the device to achieve, while a timeout value stops polling and saves wasteful battery usage when a signal or location is not available.
